As shown in FIG. 1 and FIG. 2 , the child carsafety seat 100 includes a seat body 10 and a base 20 and two lateralshock absorbers 30. The seat body 10 is installed on the base 20 foraccommodating a child. The two lateral shock absorbers 30 are disposedon two sides of the base 20. The two lateral shock absorbers 30 can beoperated to switch from a folded state as shown in FIG. 1 to an unfoldedstate as shown in FIG. 2 relative to the base 20 when the child carsafety seat 100 is installed on a car seat. During a side impactcollision, the child car safety seat 100 can collide with a car body bythe lateral shock absorbers 30, so as to transfer a side impact to thebase 20 and away from the child, which can achieve a purpose of reducinga risk of injury or death of the child due to the side impact andprovide enhanced protection for the child. However, the number of thelateral shock absorber 30 is not limited to this embodiment. Forexample, in another embodiment, the child car safety seat also caninclude only one lateral shock absorber disposed on one side of thebase.

The two lateral shock absorbers 30 have identical structures. Forsimplicity, one of the two lateral shock absorbers 30 at one side isintroduced as follows. As shown in FIG. 3 to FIG. 5 , the lateral shockabsorber 30 includes the protective fender 31, a resilient component 33and a locking mechanism 35. An end of the protective fender 31 ispivoted to the base 20, so that the protective fender 31 is pivotallyswitchable between the folded state and the unfolded state relative tothe base 20. The resilient component 33 is for biasing the protectivefender 31 to switch to the unfolded state. The locking mechanism 35 isfor selectively engaging with the protective fender 31 to restrain theprotective fender 31 from switching to the unfolded state or fromdisengaging from the protective fender 31 to allow the protective fender31 to switch to the unfolded state by the resilient component 33 whenthe protective fender 31 is located in the folded state.

In order to facilitate pivotal connections of the ends of the twoprotective fenders 31 and the base 20, the base 20 includes the twoconnecting portions 21 and a base body.

Preferably, in this embodiment, the resilient component 33 can be atorsional spring disposed on a pivoting shaft of the protective fender31 and abutting between the protective fender 31 and the connectingportion 21 to facilitate the protective fender 31 to switch to theunfolded state. More preferably, in this embodiment, a first recess 211can be formed on an upper end of the connecting portion 21 forinstalling an end of the torsional spring to facilitate operation of thetorsional spring. However, the type and the configuration of theresilient component 33 are not limited to this embodiment. The resilientcomponent 33 also can be any other resilient element and disposed in adifferent manner.

As shown in FIG. 5 and FIG. 6 , the locking mechanism 35 includes thelocking component 351 and a recovering component 353. A locking hole 355is formed on the protective fender 31. An installing hole 357 is formedon the connecting portion 21 of the base 20. The locking component 351and the recovering component 353 are installed inside the installinghole 357. Specifically, in this embodiment, the recovering component 353can abut between a bottom wall of the installing hole 357 and thelocking component 351 for biasing the locking component 351 to engagewith the locking hole 355 to restrain movement of the protective fender31. However, it is not limited to this embodiment. For example, inanother embodiment, the locking hole can be formed on the connectingportion for installing the locking component and the recoveringcomponent, and the installing hole can be formed on the protectivefender. Furthermore, understandably, in another embodiment, the childcar safety seat can further include an operating component connected tothe locking mechanism for driving the locking mechanism to disengagefrom the protective fender. For example, the operating component can beconnected to the locking component for driving the locking component todisengage from the locking hole to allow movement of the protectivefender.

Preferably, in this embodiment, the recovering component 353 can be acompression spring. However, it is not limited thereto.

Understandably, in another embodiment, the locking mechanism can furtherinclude a restraining portion disposed inside the installing hole forrestraining a displacement distance of the locking component to preventdisengagement of the locking component and the installing hole caused bythe recovering component.

As shown in FIG. 5 to FIG. 10 , in this embodiment, the lockingmechanism further includes a driving pin 359. A through hole 352 isformed on the locking component 351. A long slot 40 is formed on theconnecting portion 21 for allowing the driving pin 359 to passtherethrough. The driving pin 359 is inserted into the through hole 352by passing through the long slot 40 to be fixed on the locking component351. The driving pin 359 can be operated via the long slot 40 to drivethe locking component 351 to disengage from the locking hole 355, so asto allow the protective fender 31 to switch from the folded state to theunfolded state. Preferably, in this embodiment, the driving pin 359 canbe made of metal material and formed in a circular column, and a shapeof the through hole 352 can be corresponding to a shape of the drivingpin 359. However, the material and the shape of the driving pin 359 arenot limited to this embodiment. For example, in another embodiment, thedriving pin also can be formed in a square or rectangular column.Furthermore, the structure and the configuration of the driving pin arenot limited to this embodiment. For example, in another embodiment, thedriving pin can be configured to prevent the disengagement of thelocking component and the locking hole by insertion of the driving pininto the through hole and to allow the disengagement of the lockingcomponent and the locking hole by removal of the driving pin from thethrough hole.

Besides, understandably, in another embodiment, the child car safetyseat can further include two releasing portions disposed on a bottomportion of the seat body. The releasing portion is for driving thedriving pin to disengage the locking component from the locking holewhen the seat body is installed on the base, which simplifies operationof the child car safety seat. Specifically, the releasing portion can bea protrusion disposed on the bottom portion of the seat body and locatedat a position corresponding to the long slot, so that the protrusion canoperate the driving pin via the long slot to disengage the lockingcomponent from the locking hole to allow the protective fender to switchto the unfolded state by the resilient component when the seat body isinstalled on the base, which brings convenience in use.

Furthermore, as shown in FIG. 5 to FIG. 7 , a first guiding inclinedsurface 50 is formed on a lower end of the protective fender 31. Asecond guiding inclined surface 60 is formed on the locking component351. The locking component 351 is driven by cooperation of the firstguiding inclined surface 50 and the second guiding inclined surface 60and the recovering component 353 to engage with the locking hole 355when the protective fender 31 switches from the unfolded state to thefolded state.

As shown in FIG. 1 to FIG. 10 , operational principle of the child carsafety seat 100 of this embodiment is provided as follows.

When the child car safety seat 100 is not in use, the protective fender31 can be operated to pivotally switch to the folded state relative tothe base 20 to save occupied space of the child car safety seat 100.During the aforementioned process, the resilient component 33 can beresiliently deformed, and the locking component 351 can be driven bycooperation of the first guiding inclined surface 50 and the secondguiding inclined surface 60 and the resiliently deformed recoveringcomponent 353 to engage with the locking hole 355, so as to restrain theprotective fender 31 in the folded state. Furthermore, when theprotective fender 31 is in the folded state, the protective fender 31and the connecting portion 21 are arranged side by side due to theengagement of the second recess 213 and the first protrusion 311.

When the child car safety seat 100 is in use, the protective fender 31can be operated to pivotally switch from the folded state to theunfolded state relative to the base 20 to reduce a side impact on thechild during a side impact collision. Specifically, the driving pin 359can be operated via the long slot 40 to drive the locking component 351to disengage from the locking hole 355 for allowing the protectivefender 31 to leave away from the folded state. At this moment, theresiliently deformed resilient component 33 can drive the protectivefender 31 to pivotally switch from the folded state to the unfoldedstate relative to the base 20. Therefore, during a side impactcollision, the child car safety seat 100 can collide with the car bodyby the protective fender 31 of the corresponding lateral shock absorber30, so as to transfer a side impact to the base 20 and away from thechild, which can achieve the purpose of reducing the risk of injury ordeath of the child due to the side impact and provide the enhancedprotection for the child.
